Brain Bomb

Nice PT2399-based vibrato/chorus with a twist.

As well as your standard Speed and Depth (Blend on our PCB) controls, there's a Warp knob to play with. This sends the signal on a much wobblier course, altering the LFO as it does its thing. The results are exactly as the control would suggest, warping the signal.

There's a nice warm feel to this one. Quite organic sounding due to the PT2399's inherent modulation. Good range of speeds too, from ambient swoosh to all-out warbling.

The Warp knob works backwards, i.e. less warping the more CW you turn it. It's how it is on the original - go figure.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
